Do you know how to lookup modules? I believe my graphics driver is of the integrated Intel variety. If it's video related I'd like to try this.

Intel drivers are not proprietary, that's why all of my machines have them. Broadcom wireless drivers are proprietary... lsmod will give you a list of all modules currently loaded.

uswsusp (userspace software suspend)
is a suspend-to-ram and
suspend-to-disk implementation for the
Linux operating system, compatible
with kernels 2.6.17 and onwards. It
supports both s2ram ("standby") and
s2disk ("hibernate"), as well as a
mode called "s2both", which saves
state to disk and RAM. S2both is
intended for use in low-battery
situations where restoring from ram is
desired but can't be relied on as the
battery may fail causing a restore
from disk to be necessary.

@Nigel Thorne: it would be more helpful if you described the exact steps you did and how it manifested when it didn't work (i.e. it didn't hibernate, it didn't resume from hibernate, etc)
